STEP 1:
You need to find the area of the circular pad.
Circle Area= πr^2
we need the radius which is half of the diameter given
=π(50÷2)^2
=(3.14)(25)^2
=(3.14)(625)
=1,963.495 ft^2 total area
STEP 2:
Find how much paint is needed by dividing a can's coverage into what's needed.
=1963.495 ÷ 200
=9.817
=10 cans are needed (because you cannot buy a part of a can, you need to round up)
ANSWER: 10 cans are needed

Answer:
C
Step-by-step explanation:
a=0.15789474
b=0.1875
c=0.27272727
d=0.375
Answer:
No
Step-by-step explanation:
The equation of a circle with center (a,b) and radius r is given as:
If a given point (x,y) does not lie on this circle, it will not satisfy its equation.
This means the distance from the point to the center is not equal to the radius.
It is either less or greater than the radius.
Hence you cannot write the equation of the circle.
Answer:
23
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
- divide the given polygon into two (a square and a trapezium
- area of trapezium=1/2(a+b)×b 1/2(12+6)×12 ans 108square unit
- area of a square=s×s 12×12 =144square unit
- add 108+144=252square unit
